Psychlone is an auto sound competition format designed to capture the original excitement of a great sounding aftermarket car stereo installation. This format is also designed to cater to the vast majority of auto sound enthusiasts who design and build their systems to sound great at moderate to high listening levels. Each contestant’s sound system is scored based on how loud it will play (SPL), the frequency response of the system (RTA), and Installation Quality. These elements form the basis for a Psychlone event.

  • Sound Pressure Level (SPL) is used to determine how “loud” the stereo system can play.
  • Real Time Analysis (RTA) is used to determine the frequency response of the system.
  • Installation Quality is used to determine if the fundamental elements of good aftermarket installation are followed.
1-1 Competitors may use the program material of their choice while competing.

Additional Guidelines:

  • The program material being played may originate from any type of source unit that has been specifically designed to play music. This includes cassette decks, CD players and changers, DVD players and changers, VCR’s and VCP’s, MP3 units, AM/FM/Satellite radio tuners, smartphones, tablets, etc.
  • Both wired and wireless connections between the source unit and the sound system are permitted. This includes RCA cables, Fiber-Optic cables, Bluetooth, WiFi, etc.
  • The program material must consist of music. No “test tones” are permitted. Test tones “camouflaged” as music or “songs” that are advertised as music but are, in fact, test tones will not be permitted in competition.
  • The program media may be from a commercial source (such as a CD you purchase) or a custom, homemade recording.
1-2 Adjustments to the sound system may be made while the vehicle is being metered as long as no other applicable rules are violated during the adjustment process. (Metering is the process where the Sound Pressure Level or SPL of your vehicle is measured.)
1-3 The contestant’s vehicle may be running while in the judging lanes as long as the following conditions apply:

  • Operation of the vehicle or sound system must not endanger the judge, competitor, spectators, or any real or personal property on the premises.
  • The vehicle’s parking brake must be set.
  • The wheels must be chocked.
  • The hood must be closed.
  • The maximum engine idle speed must not exceed 2000 RPM.
  • A remote “engine kill switch” must be easily accessible from outside of the vehicle for those competitors that are bolting (clamping, strapping, etc.) the doors of the vehicle closed while in the judging lanes.

It is the competitor’s responsibility to comply with the conditions listed above. Competitors found to be in violation of one or more of these conditions may be eliminated from the competition.

1-4 The contestant must be outside of the vehicle while the sound system is being metered and all doors, windows, and other openings to the vehicle must remain closed during this time.

Exception – Competitors may remain inside of the vehicle during metering provided:

  • They wear adequate hearing protection at all times.
  • The competitor must sign a Psychlone entry form that includes a waiver stating that the competitor understands that “exposure to high sound pressure levels may result in temporary or permanent hearing loss”.
1-5 Electrical System

  • All of the auto sound equipment must be powered by the vehicle’s 12-volt electrical system.
  • Only 12-Volt automotive batteries may be used.
1-6 Installation

  • All auto sound equipment must be permanently installed within the vehicle and shall not interfere with the normal use of the passenger compartment. (The area in front of the B-pillars.)
